High Reliability
High Image Quality
The dual lamp system and lamp relay function enable
continuous operation with no risk of the image going out. Dust
resistance and cooling performance are greatly enhanced by
the automated self-cleaning filter and heat-pipe cooling system
technologies that have proven so successful in air conditioners,
enabling extended continuous use for monitoring and digital
signage applications.

For these projectors we've utilised the same mechanism (mesh filter
and cleaning brush) that has a proven track record in Mitsubishi
Electric air conditioners and airifiers. It automatically prevents dust from
building up in the radiator of the heat-pipe cooling unit for the digital
micromirror device (DMD), thereby ensuring trouble-free use for
extended periods of time.

Compared to liquid-based cooling systems, this heat-pipe cooling
system has a simplified structure and does not require a power supply,
enabling a more compact design and cost reductions. Not only is it
highly reliable, other benefits include exceptional energy savings, quiet
operation and elimination of concerns regarding liquid leaking.
Heat-pipe Cooling System
Continuous, bright projection is ensured through the utilisation of a
dual-lamp light source and a variety of setting options. When two
lamps are in use, one of the lamps can be rested (turned off) once a
day or week. Additionally, if only one lamp is being used and it goes
out, an automatic back-up function activates the other lamp, enabling
nonstop projection.
Various Lamp Relay Options
The projectors are equipped with Mitsubishi Electric’s industry-leading,
advanced image-processing algorithm, which is also used in our
televisions and displays. The technology analyses blurred components
in the original images, estimates high-resolution data not provided in the
original signal and corrects the image quality. The result is the projection
of sharp, vivid images such as people's faces in fine detail.
Super Resolution
This colour balancing function enables more precise control by allowing
each colour to be adjusted independently. Conventional R/G/B/cyan
(C)/magenta (M)/ yellow (Y) six-axis colour gradation correction has
been refined to include intermediate colours, resulting in 12-axis*
correction.

*Automatic projector-based correction in conjunction with conventional R /G/ B/C/M/Y six-axis
manual correction and intermediate-colour six-axis manual correction.
The projectors can analyse an image signal, detect the screen
brightness distribution of each scene and then automatically correct
the signal in real-time to enhance contrast. This suppresses the loss of
shadow details in dark scenes and highlight details in bright scenes,
producing clear, dynamic images.

with Dynamic Contrast Correction
The trees in the middle of the screen have a sharply defined outline, producing a distinct sense of depth.
Features including an impressive 7500lm brightness and
a high contrast of 2800:1 allow these projectors to
reproduce clear, sharp images regardless of venue size,
be it a large meeting room or lecture hall. Whether
coming from a computer, DVD player or other source,
the reproduction of vivid images full of colour is
guaranteed.
*White brightness is reduced when the optional colour wheel is used.
In addition to the standard red (R)/green (G)/blue
(B)/white (W) four-segment colour wheel, an optional
three-segment (R/G/B) colour wheel is available.
Compared to the standard colour wheel, it
reproduces each primary colour (R/G/B) with high
brightness and in vivid, deep tones, making it
possible to project visuals rich with colour.
